GAS-BURNER. a

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed December 14, 1910. Serial No. 597,386.

To all whom fit may concern.'

Be it known that I, GEORGE H. HUs'roN, a citizen o-f the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented new and useful Improvements in Gas-Burners, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in gasb-urners and relates more particularly to a burner which may be appliedto a coal stove, when it is desired to employ gas in lieu of coal orwood. Its use, however, may b-e extended to furnaces, in which case anumber of burners would be used.

The objectof the invention is to provide a new and novel form ofadjustment by means of which the size of the flame may be regulated,easily, quickly and positively.

Further and other objects will later apear.

In the drawings: Figure 1 is a side elevation, partly in sect-ion, ofthe preferred form of my invention, Figs. 2, 3 and 4 are fragmentarydetail views, in partial section and side elevation of a modified formof the invention, Figs. 5 and 6 are fragment-ary sect-ional and sideelevat-ions of a still further modified form of the invention, and Fig.7 is a section on the line 7-7 of Fig. 6.

Referring by reference characters to the drawing 1 designates the burnerbody of somewhat conical-form, which at its lower end is in threadedengagement with a short section of pipe 2, the latter being connected toan elbow 3. A lug il is carried by the elbow 3, for suitable attachmentto a suitable part of the stove whereby the device is supported withint-he latter. An air intake 5, is secured to the elbow 3, and hasconnection with a pipe 6 which leads to the source of gas supply. Airintake 5, is formed .with a series of circumferential openings 7, whichform air inlets to admit air to the body 1, of the burner. A sleeve S isrotatably mounted on the air intake 5, and is formed with air inlets 9,which are similar to the air inlets 7, of the air intake 5 and whichregister with said air inlets 7. An arcuate slot 10 is formed transverseof the length of sleeve 8 and receives a pin 11 carried by air intake 5,whereby the movement of the sleeve S, is restricted in an obviousmanner. It will be seen that by adjusting openings 9 of sleeve 8 withrelation to the openings 7 of the air intake the quantity of airadmitted to the burner be regulated at will.

The burner cap 12 comprises a top plate 13 and a marginal depending rim141 which engages over the periphery of the flange 17 of the body 1, therim 14e, being formed with a series of inverted U-shaped slots 15, theinner corners of which slots are square or sharp to thus formrectangular teeth 16, which act as efficient flame spreaders asdistinguished from those heretofore used in which round or curvedmeeting portions have prevailed. Obviously by raising or lowering thecap 12, the size of the fiame may be adjusted o-r regulated since thesize of the flame is determined by the distance between the top plate 13and the upper edge of the liange 17, of body l. A pair of verticalscrews 18 are carried by body 1, and the latter on its int-erior isformed with a seat 19, for each screw, the seat being at the base of thescrew and acting to support the burs or washers 20, which are receivedover the screws and which engage with collars 21, integral with theunder face of plate 13 and depending therefrom. The plate 13 hasapertures through which the screws 18 project and the latter receivenuts 22, to hold the cap 12, in position. It will be seen that byincreasing or decreasing the number of burs or washers 20, the distancebetween the burner cap and the body 1, may be changed or altered toadjust the size of the flame openings.

The modication illustrated in Figs. 2, 3 and 4, contemplates a differenttype of flame adjustment, the top 17 of the burner body having lugs 23,some of the teeth 16', being formed with cutaway portions which formseats 24, the latter resting on the lugs 23. It will be seen that theseats 24 in Figs. 2, 3 and 4 are at different distances from the topplate 13, whereby the cap may be turned and by bringing certaindeterminate ones of the seats in position to rest on and be s upportedby the lugs 23, the cap will be oblgiously held at different distancesfrom the ody.

Figs. 5, 6 and 7, show a still further modiflcation, wherein certain ofthe teeth 16 carry pins 25, for engagement in inclined slots 26 formedin the top 17 of the body, whereby when the cap is rotated, the cap willbe raised or lowered, according to the direction of rotation of the cap,as is maniest.

body may The under face of cap 12, is preferably provided, as seen inFig. l, with one or more depending lugs 12, which prevent the burner`cap from being moved down on the body 1,' in such manner as wouldotherwise out ofi" the gas supply from entering the slots 15. The coneshape of body l, permits the gas and air to become thoroughlycommingled.

lVhat I claim is:

l. In a gas burner, a body formed with seats on its interior, screwsextending up from the seats, washers received over the screws andengaging on the seats, a burner cap composed of a top plate and a seriesof depending rectangular teeth which engage over the burner body, saidtop plate being formed with openings and with collars which surround theopenings and depend from the top plate of the burner cap, said collarsseating on the uppermost of said washers, and nuts engaging the screwsand the top face of the top plate of the burner cap.

2. In a gas burner, a body having horizontal seats on its interior,screws extending up from the seats, washers received over the screws andengaging on the seats, a burner cap havlng openings to receive thescrews and being supported from said washers, a

slotted rim depending from the cap and engaging over the body, and lugscarried by the cap for engagement with the body to restrict the downwardmovement thereof.

3. In a gas burner, a body having an upwardly extending flange, a topplate having a depending flange engaging over said flange of the body,said plate flange being formed with spaced teeth, means for adjustingthe distance between the plate and body, and means carried by the topplate for engagement with the top edge of said flange of the body toprevent said plate from seating on the body and thereby cutting ofi thesupply of gas to the spaces between said-teeth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
